Hirnbioelektrische Untersuchungen zur Frage der a-Wellen beim Kaninchen *

D fruchtbare Weiterentwicklung der hirnbioelektrischen Forschung wird dadurch behindert, daß die Ergebnisse der tierexperimentellen Untersuchungen mit den am Menschen gemachten Befunden immer noch nicht völlig in Übereinstimmung gebracht werden konnten. Denn da man beim Menschen im wesentlichen auf die Ableitung der durch die Kopfhaut erfaßbaren, von der Hirnrinde der Konvexität stammenden Pote...

It can develop before the symptoms of anemia is obvious, with myelin injury and then axon and even neuron destruction in spinal cord, brain, optic and peripheral nerves.

There are many possible reasons for our inability to make progress. One possibility is that our efforts thus far may n...

Trans-synaptic Retrograde Degeneration in the Visual System of Primates.

From an experimental point of view it is not a particularly attractive field for study due to the time required for the full effects to become evident and may entail many months or even years of waiting. Consequen...
